Week 5 Journal!
USA, California, Sacramento County, Antelope (Appears as Roseville on some of the observations, but this is because the area is kind of on the border of the two cities), 38°43'29.3"N 121°23'40.7"W, 25m, 04 May 2020 Coll: K. Ball

The day was warm and clear, and the winds were low. By the time evening rolled around, it cooled down quite a bit, but it wasn’t cold by any means. Still a comfortable cool / slightly warm (if that makes sense). For this outing, I tried to get out earlier to try and see more insects out in the warmer parts of the day. Since things are getting close to the end, I decided to stay out for several hours to catch as much as I could. At this point, many of the flowers in this field are withering away, and many of the grasses are dying out. It is definitely easier to walk around here, as it seems many of these really annoying spiky green plants that can poke you through jeans are gone.
My goal was to skip over the part of this site that I have already spent a lot of time in, but I kept seeing many insects I had not yet caught or observed, so I spent a solid couple hours in the field area in proximity to the side of the road. It was easier to access some different areas and plants/trees with some of the field dying back. Many leaf hoppers, ladybugs in various life stages, hoverflies, especially on/near flowers, and plant bugs, as per usual. A LOT of leafroller tortricidae moths were flying about and resting inconspicuously on the underside of leaves. Found this one large plant with tiny white flowers that had a lot of carpet beetles on them. I also saw a snake fly hanging out on a leaf here but missed it! Luckily I stumbled across another one flying around out in some grasses I sat in a little later. On a nearby plant, I saw this wildly patterned bug I thought was a plant bug but turned out to be a bush katydid! On a nearby tree I noted what seems to have been a chalcid wasp, but my only pics of it aren’t great and it flew away before I could try to catch it. One plant I wandered by had LOADS of aphids on it. May have had some other insects mixed in with them, but I haven’t had a chance to take a look at the ones I collected and post up to Inat. There was a ladybug chillin’ on top of one of the densely packed portions of the stalk having a field day!
Pressing deeper into the field, close to where it slopes down to a trail that runs under the road I came from and towards creek access, there were still many tall grasses alive and well and a few flowering plants still holding on to their vitality just beyond a patch of mostly dying grasses. Saw some butterflies flying around here, including more California Pipevine swallowtails, a bright yellow butterfly, and this really cool red white and black butterfly that perched high on a large leaf (I elected not to post my pics of this one because the colors don’t look right in the picture on account of the zoom and distance). In some dead grasses, I found another hair-covered caterpillar of the same sort I found on my last trip, a pupa I can’t identify, and a darkling beetle in a sandy/coarse substrate patch amidst the dead grasses. Also around this area, I managed to catch one of the many mayflies that were out and about this outing (it’s an American rubyspot), a black plant bug with swollen black lobes on one of their antennae segments, a click beetle, and a leaf beetle that looks like a grey ladybug. On a LARGE tree leaf I also found some LARGE soldier beetles that caught my eye.
Moved down the slope onto the trail that runs under the road I entered from. A LOT of mayflies congregating on the damp dirt. Caught a harlequin bug on a plant, saw another hairy caterpillar on a mossy log, caught another, smaller, soldier beetle that looks a lot like the large ones I found, and caught a few miscellaneous dipterans I haven’t identified and posted yet (look like muscidae and hoverfly though) and saw a few I didn't capture or photograph. At the creek I saw another american ruby spot with beautiful red patches on its wings, an earwig with really large, rounded pincer-like cerci, and caught what may have been a water strider?? Haven’t looked at it more closely since catching it/haven’t put it on iNat. It’s rather small, but I did catch it as it went from sand to walking on the water…. Shortly after this catch some guy who seemed to own a home on the other side of the creek told me I was trespassing and seemed quite annoyed by my presence. I kind of wish I tried to talk him into letting me stay for like 15 more minutes because I was JUST STARTING TO GET AROUND TO LOOKING IN THE WATER and there was a white butterfly in the area I was hoping to catch. But… he seemed annoyed and I didn’t wanna press my luck so I headed back the direction I came from. On my way back out to the road, more or less retracing my steps, I saw two flies mating and caught them. They might be tachinidae, but I can’t quite tell. I have to spend more time looking at them. Also caught a couple little snout beetles on some plants on my way out.

Species account:
The species that caught my eye most this trip was probably the pieridae butterflies that I sporadically saw around in the field. I feel like I’ve seen a few of these around in my yard in the past, and I think they’re quite pretty. Definitely not as showy as the other butterfly species, but there’s something kind of pretty about their simplicity. I kept seeing these guys around my past couple outings to this area, but I never got the chance to really get close enough to one to try catching it. They’re always just out of reach or fly way far away before I get a chance to move closer. This includes one I was trying to follow around by the creek before being told I was trespassing ;-;. BUT the one I caught caught my attention in particular because of the circumstances around its capture. I was walking up the side of the road back to my house, erring on the side of walking through some tall grasses to be as far from the pavement as possible. One patch of grass I kicked through ended up startling one of these out! I instantly dropped all my things into the field and went after it with my net. Luckily, and I don’t know if its because these are weaker fliers or this one was just a little disoriented, I managed to net it out of the air after a couple attempts before it had a chance to escape to a field on the other side of a fence. I also got a little diptera in my net with it as a bonus.
